Abstract

Simulation models of power-supply systems with sources based on gas-turbine units with different structures and compositions of components and analysis of their functioning taking into account various technological factors and specifics of the power system are considered. The calculation of the dynamic conditions is represented as a sequential calculation of the static modes at each sampling step. Models of power-supply system components have been developed, including a nonlinear model of a gas-turbine unit and a model of the source of nonlinear distortions. The presented method for calculating the parameters of the models of power-supply system components allows one to model complex modes of power-supply systems powered by autonomous sources. For verification of the calculations, a seminatural model was developed based on the laboratory “synchronous motor–dc motor” setup. The approach proposed makes it possible to improve the accuracy of modeling interrelated processes and to expand the range of the tasks to be solved including modes that are not recorded by instrumental measurements. The results of the scientific and engineering solutions implemented in industrial conditions have good convergence confirmed by seminatural models and instrumental surveys.

以燃气轮机为能源的电源系统建模

摘要

考虑了基于具有不同结构和组成成分的燃气轮机的电源系统的仿真模型，并考虑了各种技术因素和电力系统的特点对其功能进行了分析。动态条件的计算表示为每个采样步骤的静态模式的顺序计算。已经开发了电源系统组件的模型，包括燃气轮机机组的非线性模型和非线性畸变源的模型。所提出的用于计算电源系统组件的模型的参数的方法允许人们对由自主源供电的电源系统的复杂模式进行建模。为了验证计算，根据实验室的“同步电动机-直流电动机”设置开发了半自然模型。所提出的方法使得有可能提高对相关过程建模的准确性，并扩大要解决的任务范围，包括仪器测量未记录的模式。在工业条件下实施的科学和工程解决方案的结果具有很好的收敛性，这已通过半自然模型和仪器调查得到证实。
